Answer:
y + 1 = 4(x + 3)
Step-by-step explanation:
Use the point-slope form of the equation of a straight line:
y - k = m(x - h), where (h,k) is a point on the line:
Here,
y + 1 = 4(x+3) (Answer 2 on the list)
Hi there!
One and one tenth looks hard but that would be because it's in word form.
In standard, or decimal form, this would be 1.1.
The first 1 represents the whole number and the second 1 represents the tenths.
Hope this helps! Let me know if you need anymore help! :)
I think your answer would be B

Answers: Choice C and choice D</h3>
y = csc(x) and y = sec(x)
==========================================================
Explanation:
The term "zeroes" in this case is the same as "roots" and "x intercepts". Any root is of the form (k, 0), where k is some real number. A root always occurs when y = 0.
Use GeoGebra, Desmos, or any graphing tool you prefer. If you graphed y = cos(x), you'll see that the curve crosses the x axis infinitely many times. Therefore, it has infinitely many roots. We can cross choice A off the list.
The same applies to...
- y = cot(x)
- y = sin(x)
- y = tan(x)
So we can rule out choices B, E and F.
Only choice C and D have graphs that do not have any x intercepts at all.

If you're curious why csc doesn't have any roots, consider the fact that
csc(x) = 1/sin(x)
and ask yourself "when is that fraction equal to zero?". The answer is "never" because the numerator is always 1, and the denominator cannot be zero. If the denominator were zero, then we'd have a division by zero error. So that's why csc(x) can't ever be zero. The same applies to sec(x) as well.
sec(x) = 1/cos(x)
B. 16=n*32; 50%
Step by step explanation:
16 divide 32= 1/2
1/2*100= 50
